This is happened to me a 1000 times and im ticked off.
When logging in or when I do some work on my SACE my (H:) at school keeps going down. None of my classmates have any problems neither does the school it seems its affecting me badly.

Error Message:
H: Not Accessible
Connection could not be resolved.

This happened already twice today actually the third time! My admin is scratching his head wondering what the hell is going on
And he said plug the ethernet cord in did that plus logged out logged back in and it does it in 5 seconds and I cannot access any files.

It sounds like your computer is having networking issues in connecting to the school's server (your H: drive). Are you using WiFi to connect, or wired ethernet?
